What plugin can change the dates of posts on my WordPress blog????

 

You don't need a plugin. Just edit a published post and change the Publish Date.

 

See Published on:, then edit it.

 

And how to hide Last edited date?
You see, I want to make the new blog, visitors to think, that it is already living for a year)

 

You may remove this code :

on single post, and remove this code :

on main index template..

But, Don't forget to back up ur theme first

 

Thanks arramuse! That`s what I need)
